If you need to switch power to a device without the hassle of a big expensive relay, this Relay Phidget is here as a quick an easy option. Rated for 210W of DC power or 1750 VA of AC power, this mechanical relay is suitable for a wide range of applications. Relays by nature are isolated, so you don't have to worry about a voltage spike on the load side of the relay damaging the control side. If mechanical relays are too slow or noisy for your purposes, have a look at the Other Relays tab and chose a solid-state relay (SSR) board.

AC or DC Switching

For DC applications, you can switch a circuit of up to 30V at 7A. For AC applications, you can switch up to 12A or 277V AC, as long as the total power doesn't exceed 1750 VA.

VINT Hubs and InterfaceKits

This Phidget can be controlled by a VINT Hub or any other device with a digital output. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs and Phidget InterfaceKits that can be used with this device:

Phidget Cables

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

First Look

After plugging the REL2001 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

Serial number: allows you to differentiate between similar Phidgets.

Channel: allows you to differentiate between similar objects on a Phidget.

Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Digital Output

Double-click on a Digital Output object in order to run the example:

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

Toggle the state of the digital output by pressing the button.

Note: the REL2001 is not designed to be used with Duty Cycle.

Technical Details

General

A relay is an electrically-controlled switch. For more information about how mechanical relays work and how to use them, check the Mechanical Relay Primer.

Use with an Interface Kit

In addition to plugging directly into VINT ports, the REL2001 relay can be used with Interface Kits that have a Digital Output and 5V supply (like the 1018).

To connect the REL2001 to the Interface Kit, cut one end off a Phidget Cable. Connect the red and black wires to the 5V and G terminals of the Interface Kit, respectively, and the white wire to the OUTPUT terminal you want to control the relay. Plug the end that still has a connector into the REL2001.

To control the relay, open the DigitalOutput object for the channel the white wire is connected to. Setting the output state TRUE or FALSE will set the state of the relay.

What to do Next

Phidget22 API - The API is a universal library of all functions and definitions for programming with Phidgets. Just select your language and device and it'll give you a complete list of all properties, methods, events, and enumerations that are at your disposal.

This device doesn't have an API of its own. It is controlled by opening a DigitalOutput channel on the Phidget that it's connected to.
For a list of compatible Phidgets with Digital Outputs, see the Connection & Compatibility tab.

You can find details for the DigitalOutput API on the API tab for the Phidget that this sensor connects to.

*Note: Switching this relay at voltages higher than 30V will result in a reduced product lifespan.

Please Note: This relay cannot be switched at its maximum AC voltage and current at the same time. Ensure that total power of the load does not exceed the switching power for the relay. For example, you can switch this relay at 277V AC and 6.3A (1750VA), or at 145V AC and 12A (1750VA), but not at 277V and 12A (3324VA).

Estimated Relay Lifespan

The lifespan of the relays on this Phidget vary depending on how much current you're switching and whether it's AC or DC. The following graph illustrates the relationship between load current and relay lifespan:

The vertical axis is the lifespan of the relay (number of actuations) and the horizontal axis is load current in amps. As you can see, increasing load current from 5A to 10A can reduce relay life by more than half.
